GeForce GTX Titan review

We test and review the GeForce GTX Titan. The GeForce GTX Titan is NVIDIAs fastest single GPU based graphics card they have ever built. It is based on the GK110 GPU and has an astonishing 7.1 Billion transistors and is as such is nearly as fast as one GeForce GTX 690 with two GTX 680 GPUs ! We test the product with the hottest games like Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more. Next to that with the three samples we have at hand we'll be looking at SLI performance scaling in another article as well.

AMDs fps numbers are overstated. They figured out a trick to make runt frames, or frames which are not actually rendered to trigger the fps monitor as a real fully rendered frame. This is real problem for AMD much worse than the latency problem. Crossfire is a disaster which is why numerous reviewers including Tech Report have written that Crossfire produces higher fps but feels less smooth than Nvidia.
Check this article out. http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GeForce-GTX-TITAN-Performance-Review-and-Frame-Rating-Update/Frame-RatAbout the fully rendered frames and whatnot, oh really? Why do I experience heavy microstutter if I'm at 60-67FPS without VSync On, but absolutely NO microstutter whatsoever with VSync ON at 60FPS? Both cards would be in the 90%+ GPU usage, which is pretty close to where they were before I VSynced. Plus it stays microstutter-free as GPU usage increases (instead of dipping from 67 to 65 to 62-61 with VSync off), and maintains a constant 60FPS.

Cards are scaling, they're delivering the reported FPS, but it's the microstutter phenomenon itself that is the issue.

Heaven benchmark 3.0 was what I tested with.

I did check the link, it definitely speaks to frametimes, and it's not a difficult jump to figure that the same thing that causes a frame to take 2x-5x as long to render, but not affect FPS, is the same problem you're seeing here.

Think about it, the lag spikes players and these frametime benchmarks see, where does that time go? How is it possible that the GPU renders a scene, there is a perceptible lag time when a frame takes longer to render, but FPS is unaffected? It's because the frame gets stuck, though the frame behind it (after it) is still rendered, but never displayed. That's why you see this sliver frame, because the GPU rendered it, but by the time the previous frame got out of the buffer, it was no longer needed.

If the previous frame doesn't get stuck, as indicated by the long solid stripe in their measurements, then that next frame will be displayed properly.

I've seen entirely different phenomena - smooth, even frametimes, smaller than 16ms, yet stuttering and feeling like 20fps.
How would you explain that?
That's right - frame skipping, which is not entirely different compared to what we have here.

Check my reply above please. It targets this idea.

well... wild local frametime variations are usually called micro stuttering when dealing with multi-gpu, but the same phenomena exists on single GPUs.
we usually refer to it by just stuttering

Gentlemen, may I ask thee kindleeeh to please get back on topic, which was the GeForce GTX Titan release.

Also to keep lower TDP, if it were 1Ghz then it would be more then 250W.

Kinda ridiculous to see a enthusiast grade card with such a low TDP, honestly.

I'm not interested in this card for gaming, but as a 3D artist.
I cannot find any test of the titan showing it's performance in cuda, in particular Vray RT.
Guru3D or any other - would it be possible for you to test this?

I think many in the visualization community would be very pleased to see these results :-)
